我目前使用Vue.JS 2.0,我想从一个自定义指令更新一个Vue实例的模型,但是我看起来很好的方法,这是因为我试图创建一个实现JQueryUI-Datepicker代码的自定义指令如下:

<input type="text" v-datepicker="app.date" readonly="readonly"/>

Vue.directive('datepicker', {
  bind: function (el, binding) {
    $(el).datepicker({
      onSelect: function (date) {
        //this is executed every time i choose an date from datepicker
        //pop.app.date = date; //this work find but is not dynamic to parent and is very dirty
        Vue.set(pop, binding.expression, date); //this should work but nop
      }
    });
  },
  update: function (el, binding) {
    $(el).datepicker('setDate', binding.value);
  }
});

var pop = new Vue({
    el: '#popApp',
    data: {
        app: {
            date: ''
        }
    } …
